Here are four new icons of Mac OS X 10.7 Lion.
Mac App Store
I don't own any graphic.
Facetime and Mac App Store images belong to "Cyzor" from Wikipedia,
Launchpad icon and Lion screen taken from xXmatt69Xx1
And iTunes 10 from pachiderma
I just changed the format of the files. I created a PNG, a ICO and a ICNS format of every icon.
